Sura al-Ḥajj 22:63

أَلَمْ تَرَ أَنَّ ٱللَّـهَ أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءً فَتُصْبِحُ ٱلْأَرْضُ مُخْضَرَّةً إِنَّ ٱللَّـهَ لَطِيفٌ خَبِيرٌ

a-lam tara annā allāha anzala mina l-samāʾi māʾan fa-tuṣbiḥu l-arḍu mukhḍarratan inna allāha laṭīfun khabīrun

Seest thou not that Allah sends down rain from the sky, and forthwith the earth becomes clothed with green? for Allah is He Who understands the finest mysteries, and is well-acquainted (with them).
